Ockham affirms that a human being consists of three really distinct forms that exist in matter, thus defending a «pluralist» position in the debate about the soul. However, he takes a «unitarist» position with regard to the rational soul, claiming that intellect and will are not really distinct. Why does he not admit a plurality of forms in the rational soul as well? And why does he think that the rational soul as a whole is really distinct from the sensory (...) soul? This paper examines these questions, thus analyzing Ockham’s metaphysics of the soul. It pays close attention to his arguments both for a plurality of forms and for the unity of the rational soul. It argues that Ockham carefully distinguishes between forms that are metaphysical parts of a human being, and faculties that are ways of acting of a specific form. This distinction enables him to reject both a radical unitarism that accepts one single form in a human being, and an excessive pluralism that posits as many forms as there are faculties. (shrink)

Spinoza's metaphysical thesis that there is only one substance in the universe but a plurality of modes, each of them falling under an attribute, raises a crucial question. How are modes of thinking, i.e. ideas, related to modes of extension? This paper intends to show that there are at least two answers, depending on an understanding of the equivocal term ‘idea’. If ideas are taken to be mental acts, they are identical with modes of extension. If, however, they are understood (...) in the “objective” way, namely as the conceptual content of mental acts, they correspond to modes of extension. It is argued that this method of disambiguating the term ‘idea’ not only helps to understand Spinoza's famous doctrine of parallelism but that it also provides a solution to two puzzling problems: the possibility of “active affects” and the existence of an eternal mind.

Late medieval and early modern commentaries on De anima are Janus-faced texts. They look backwards, continuing ancient debates about well-known Aristotelian topics, and forwards, introducing new concepts and methodological principles that pave the way for non-Aristotelian theories of mind. The eleven essays in this volume, which cover the period between the late thirteenth and the early seventeenth centuries, elucidate this double orientation by presenting case studies of Aristotelians who engaged in discussions about classical issues and thereby opened the door to (...) new theories such as materialism and substance dualism. The papers do not aim at providing a survey of the commentary literature, but focus on specific texts. Some of them deal with often neglected sources. Thus, Olaf Pluta presents a detailed analysis of Nicholas of Amsterdam’s Questions on De anima and nicely shows that one can find a form of “soft materialism” in his philosophy of mind. For Nicholas rejected the thesis that the intellect is a separable, immaterial entity, claiming instead that intellectual states are always dependent on material ones without being reducible to them. Other papers provide a fresh re-interpretation of well-known texts. (shrink)

Medieval philosophers clearly recognized that emotions are not simply "raw feelings" but complex mental states that include cognitive components. They analyzed these components both on the sensory and on the intellectual level, paying particular attention to the different types of cognition that are involved. This paper focuses on William Ockham and Adam Wodeham, two fourteenth-century authors who presented a detailed account of "sensory passions" and "volitional passions". It intends to show that these two philosophers provided both a structural and a (...) functional analysis of emotions, i.e., they explained the various elements constituting emotions and delineated the causal relations between these elements. Ockham as well as Wodeham emphasized that "sensory passions" are not only based upon cognitions but include a cognitive component and are therefore intentional. In addition, they pointed out that "volitional passions" are based upon a conceptualization and an evaluation of given objects. This cognitivist approach to emotions enabled them to explain the complex phenomenon of emotional conflict, a phenomenon that has its origin in the co-presence of various emotions that involve conflicting evaluations.
